In November of 1987, engineers from the Qty of Carlsbad redesigned the road improvement area to include two additional impact areas, one on the west end of the original improvement corridor and one area, on the east end of die corridor. The westem impact area is on the south side of Palomar Airport Road, adjacent to Paseo del Norte near the westem boundary of the improvement area. The eastem impact area is also on die soutii side of Palomar Airport ^ Road, just east of Uurel Tree Lane. Pedestrian survey of these proposed impact areas resulted in die relocation and enlargement of previously recoided site SDi-10670 (W-117). near die western impact area and tiie identification of one additional cultural resource site (PAR-1) in. die vicinity of tiic eastem impact area.

Flaked lithic debris #as also noted on the site surface. Based on surface observations tiic site area u WRwimately 180 feet EW by 120 feet NS. No determination of subsurface site size wu made. Native oaks are present on site. This site is witiiin tiie proposed impact area for associated road improvements (storm drain construction) and it is recommended that thc site tcsietf la detennine significance prior to projea ^)provai. Recommended testing would be limited to the excavation of shovel test pits (STP's) to determine the site boundaries, and die excavation of not more dian four. 1 by 1 m units to sample and assess die resource area. ii SECTION 1 INTRODUCTION 1.1 PROJECT DESCRIPTION WESTEC Services. Inc. conducted a literature review for archaeological resources and completed a field survey of die original 1.5-mile project corridor in partial fulfillment of C:EQA requirements (as amended in 1984). in June of 1987 (Cheever and Gallegos 1987). The addition of two previously unsurveyed impact areas was made in O:tober of 1987. Archaeologists from WESTEC surveyed diese new areas on October 30.1987. 1.2 PROJECT LOCATION AND ENVIRONMENTAL SETTING The project is located in the west central region of die City of Carlsbad. The impact areas, as currently planned, are on die westem end of a 1.5-miIe segment of Palomar Airpon Road between Paseo del None and CoUege Boulevard (Area 1) and on die eastern end of die same road segment (Area 2). Botii of tiiese impact areas are on die soudi side of Palomar Airport Road (Figures 1 and 2). Area 1 improvements are confined between Station numbers 30-K)0 and 45+00 and range between 160 to 20 feet in widdi This area, as currentiy planned, wiU be a temporary detour road. The environmental setting in die vicinity of Area 1 consists of die base of a marine terrace or ridge diat has been cut by die construction of Palomar Airpon Road. Vegetation is primarily introduced grasses and herbs and portions of tiie area have been used for agriculture. Surface disturbance across Area 1 exists in the form of din roads and tire furrows. Area 2 is on die soudi side of Paiomar Airpon Road, just east of Laurel Tree Lane. As currentiy planned, tius area wUl be impacted by construction of a stomi drain. Area 2 includes ponions of relatively fiat canyon bottom, adjacent to a creek. The soil is alluvial and tiiere are low. marine tcnaces making up tiie remainder of die existing landforms. Ponions of Area 2 have been disturbed by grading and unautiiorized dumping, while other areas appear to be undisturbed. The vegetation in the area is characteristic of disturbed areas generally, consisting of non-native herbs, grasses, and diisties. However diere are stands of Coast Live Oak and Elderberry trees in die undisturijcd ponions of die impact area. I-l • f s I I I ^— SAN* . MLLMOOK OCIANitOI VISTA PflOJCCT LOCATION KUCAOlAi O > •z.

Inc SECTION 2 BACKGROUND INFORMATION 2.1 CULTURE HISTORY In prehistoric tinies. the Carlsbad area was occupied by at least three, somewhat distinct culture groups. These people are Icnown as the San Dieguito, La Jolla. and Luiseno Native American people have occupied San Diego County from approximately 10.000 years ago through the present day. A detailed culture history of San Diego County IS available upon request from WESTEC Services. Inc. 2.2 RECORD SEARCH RESULTS Site record searches and Uterature reviews were conducted at the San Diego Museum of Man data repository and at the South Coastal Infonnation Center at San Diego State Umversity. These record searches resulted in the identification of one previously recorded archaeological site SDi-10670 (W-117). Thi, site is on the north side of Palomar Airport Road and adjacent to the project area. The site is located in the vicinity of Area 1 and is only partiaUy within the pitjposed impact area. SDi-10670 (W-117) is recorded as a sparse artifact and shell scatter which has been disturbed by agricultural activities (Rogers site record form n.d.). An updated site form prepared by archaeologists from RBR & Associates listed surface anifacts, on the north side of Palomar Airport Road These artifacts were described as spUt cobble scrapers and flakes of various geologic materials (Gross « al. 1987). The metates and "digging weight" or "large bead" noted on the onginal site record fonn by Rogers, were not relocated (Gross 1987). It was not uncommon for Rogers to collect unique or diagnostic artifacts for curation at the San Diego Museum of Man. 2-1 SECTION 3 FIELD METHODS AND RESULTS 3.1 SURVEY METHODS Fieldwork was conducted by Andrew Pigniolo and Dennis Gallegos in October of 1987. The survey mediods applied during die field investigation conform to tiie guidelines and requirements of die Society of Califonua Archaeology (King et al. 1973) and tiiose outiined by die National Park Service (Scovill et al. 1972). Thc project areas were surveyed on foot at an interval of 5 m. as tenain and vegetation pennitted. All areas were carefuUy examined for cultural debris, and road cuts and natural drainages were checked for indications of subsurface archaeological deposits. Ground visibiUty averaged 50 percent in bodi areas witii vegetation and soU fill obscuring the ground surface in some areas. 3.2 SURVEY RESULTS Field survey of Areas I and 2 resulted in die identification of an extension of archaeological site SDi-10670 (W-117) widiin impact Area 1 and die location of one new cultural resource site PAR-1 witiiin Area 2. The ponion of SDi-10670 extending witiun tiie cunent project area consists of approximately 100 fragments of sheUfish remains including; Chione sp., Donax sp.. Mytilus sp.. Argopecten sp.. and surface anifacts. Additionally, sheUfish remains were noted in a eartiien slope cut, adjacent to Palomar Airpon Road. The shcU deposit was evident to a maximum depdi of 15 cm below die ground surface. Artifacts coUected from die site surface include 19 flakes and/or fragments of angular waste and one unifacial, riiyoUte mano fragment (Table 1). TTiese artifacts were mapped on a 1 "=40' map prior to coUection and were cataloged according to die procedures accepted by local instimtions. These anifacts are curated in die WESTEC Services Inc.. Cultural Resource Laboratory. Newly reconied site PAR-1 is witiiin impact Area 2 (see Attachment A for die site record fonn submitted to San Diego State Umversity and die Museum of Man). This site is a sheU midden witii a surface scatter of approximately 20 Udiic artifacts categorized as flakes and angular waste. These artifacts were not collected. The site area measures approximately 180 feet EW by 120 feet NS, Based on erosional cuts the shellfish deposit appears to 3-1 extend to a depth of over 40 cm below the ground surface. The represented shellfish spec.es « the madden are dominated by Chione sp. and Argopecten. sp. Portions of the site has b^dut^bed by the dumping of soU fill, off site grading for a road widening, and extensive roden, bunowing. TTie remainder of the site appears to be in good condition 3-2 Table 1 SDi.10670 (W.H7) COLLECTED SURFACE ARTIFACTS 4 or 5 6 7 8 9 10 1 1 1 2 Flake Flakes Metavolcanic Angular Waste Metavolcanic Angular Waste Metavolcanic Unifacial Mano Rhyolite fragment Flake Flakes Metavolcanic 8.4 grms Metavolcanic/ n.4grms Piedra del Lumbre Chen Discarded Flakes Metavolcanic Angular Waste Metavolcanic 10.5grms 1.5grms 381.4grms 2.4grms Metavolcanic/ 3.2gnns Piedra del Lumbre Chen 77 grms 0.3 grms 3-3 SECTION 4 IMPACTS AND RECOMMENDATIONS 4.1 IMPACTS AND RECOMMENDATIONS The fie d survey resulted in the identification of a ponion of a previously recorded archaeological site within Area 1 and a newly recorded site.

Scovill. Douglas, Hariand J. Gordon, and Keith M. Henderson R-l Exhibit 1 SCOPE OF WORK Palomar Airport Road Improvements October 22. 1987 Task 1: Archaeology WESTEC will conduct an archaeological field investigation for the detour road and channel improvements (800 feet+/- ) for Palomar Airport Road Expansion. The archaeology report prepared for the Palomar Airport Road alignment project will be amended to include the results of this reconnaissance. Task 2: Biological Reconnaissance WESTEC will conduct a biological assessment of the project site and update the Palomar Airport Road alignment report. WESTEC will prepare an impact analysis report suitable for submission to City Planning staff and regulatory agencies (U.S. Army Corps of Engineers, California Department of Fish and Game and California Coastal Commission). Task 3: Conceptual Mitigation Plan WESTEC will prepare a conceptual biological mitigation plan for impacts related to the entire road alignment, channel and detour road project. WESTEC will consult with the City to determine suitable areas for mitigation and then prepare the conceptual plan for submittal to the City Planning staff and regulatory agencies for support of permit applications. Task 4: Agency Consultation WESTEC will coordinate with City of Carlsbad staff and regulatory agencies for permit acquisition support. Included in this task will be the preparation of applications for the regulatory agencies and negotiations and consultations with the agencies. WESTEC will meet with agency representatives, as necessary, to support the mitigation program. This task will be billed separately from the other tasks described above. The estimated break-out for staffing allocation of time for this task includes 80 hours of Project Manager (B. Dehoney) and 30 hours of Staff Biologist (P. Gordon-Reedy). SCHEDULE WESTEC will conduct the field reconnaissances within three weeks of contract authorization. Mitigation plans and agency consultation will follow. COST PROPOSAL WESTEC's cost estimate for this scope of work is as follows: Task 1: Archaeology $ 500 Task 2: Biological Reconnaissance $2000 Task 3: Conceptual Mitigation Plan $3000 Task 4: Agency Consultation $4500 WESTEC will not exceed $10,000 without specific authorization by the City of Carlsbad. WESTEC's offer to complete the scope of work and cost estimate may be accepted at any time within the next 30 days. After that date, the cost estimate may need to be revised to reflect possible increased expenses. ADDITTONAL WORK Any effort to accomplish additional work beyond the aforementioned tasks can be handled through a supplemental agreement. If the agency consultation task experiences complications and man hours expended exceeds that estimated above, a supplemental agreement will be required. Also, if agency meetings and/or hearings are held outside the San Diego/Los Angeles area costs associated with travel will either be provided by the City or as added costs.
